product description
Wafer check valve is mainly used in industries such as fire protection, petrochemicals, textiles, papermaking, and high-rise buildings for the well of the water supply and drainage pipe network or the outlet of the water pump. It is a safety device to prevent backflow pressure and water hammer impact from the pipeline medium when the water pump stops and the water pump reverses.
Product Advantages
1、Small size, light weight, compact structure and convenient maintenance;
2、The valve plate is of dual type, which can close quickly under the elastic moment of the spring.
3、Due to the fast closing effect, it can prevent the medium from backflowing , and eliminate the strong effect of water hammer;
4、The valve body structure has small length, good rigidity, safety and reliability;
5、Surface coating: Epoxy powder coating is adopted, with strong adhesion and good weather resistance. It can be used indoors and outdoors.
6、The numerically-controlled machine tool grinds the sealing surface of the body, with good flatness and surface roughness, which can ensure the zero pressure sealing of wafer check valve.
7、The rubber and valve body are joined by vulcanization process, and the adhesive strength is higher than 1.7mpa, and it can avoid the falling off of the valve seat during use
